3. Product Features

• 3-in-1 Multifunction: Combines neck support, vibration massage, and heat therapy for comprehensive tension relief in the neck, back, and shoulders.
• Ergonomic Body Contour: The 23.2-inch curved design with a 15° incline fits the spine’s natural S-shape, reducing pressure on the neck and lumbar region. This design promotes proper spinal alignment.

4. Setup Instructions

1. Unpack the GDSAFS 3-in-1 Back Massager and ensure all components are present.
2. Locate the included 5V/2A power adapter.
3. Connect the power adapter to the massager's power input port.
4. Plug the power adapter into a standard electrical outlet (100-240V compatible).
5. Place the massager on a flat, stable surface where you intend to use it (e.g., bed, sofa, floor).

5. Operating Instructions

1. Once plugged in, lie down or recline comfortably with the massager positioned under your neck, lower back, or shoulders, aligning with your spine's natural curve.
2. Press the power button on the massager to turn it on.
3. Use the control buttons to select your desired massage mode (vibration, heat, or both) and intensity. The device features intelligent pressure sensing to adjust intensity based on your body weight.
4. Use the massager for up to 15 minutes per session. The device has an auto-shutoff feature for overheat protection and to prevent overuse.
5. For optimal results, use the massager regularly, such as at nighttime before bedtime, or during periods of rest while traveling or commuting.
6. Do not use the massager while sleeping.

6. Maintenance

• The massager features a removable cover with a zippered design.
• To clean, remove the cover and machine wash it according to the fabric care instructions (typically cold water, gentle cycle).
• Do not wash the main massager unit. Wipe it clean with a soft, damp cloth if necessary.
• Ensure the massager is completely dry before reattaching the cover and storing.
• Store the massager in a cool, dry place away from direct sunlight.

7. Troubleshooting

• Device not turning on: Ensure the power adapter is securely plugged into both the massager and a working electrical outlet. Verify the outlet has power.
• No heat or vibration: Check if the specific functions are activated using the control buttons. Allow a few minutes for the heat function to reach its operating temperature.
• Uncomfortable massage: Adjust your position on the massager. The intelligent pressure sensing feature adapts to your body weight, but repositioning can optimize comfort. Ensure you are not using it for more than 15 minutes per session.
• Device overheats: The massager has built-in overheat protection and will automatically shut off. Disconnect from power, allow it to cool down for at least 30 minutes, and then try again. If the issue persists, contact customer service.
